Hi,

I have a table structure as below:

C_CODE, P_61, P_62, P_63

I want to fetch C_CODE column value.

For example, If input value contains 61 then I have to use P_61 column and I have to fetch appropriate C_CODE column value. If input value contains 62 then I have to use P_62 column and I have to fetch appropriate C_CODE column value and so on. Please help me to write the above mentioned scenario in a single query.

Thanks in advance.

What do the columns P_61, P_62, P_63 contain?
Just wanted to know how you want the query when your input is 61.

If my input is 61, I have to check whether P_61 contains X or not, If my input is 62 I have to check whether P_62 contains X or not and so on..and I have to retrieve C_CODE value also.

Thanks,
Soundar.

Try this

Code:
when (:input = '61' and p_61 = 'X')
    or (:input = '62' and p_62 = 'X')
